Cultivation of three medicinal mushroom species on olive oil press cakes containing substrates | Gojenje treh vrst medicinskih gob na substratih vsebujočih oljčne tropine

English. Olive oil press cakes (OOPC) represent a waste that has a negative impact on environment. OOPC have little or no use and because of that solutions for their alternative use are sought after. In our experiments we investigated substrate mixtures composed of different proportions of OOPC, wheat bran, crushed corn seeds and beech sawdust for cultivation of Ganoderma lucidum, Lentinula edodes and Grifola frondosa fruiting bodies. The increasing amount of OOPC in fruiting bodies cultivation substrates resulted in decreasing production of fruiting bodies. Results show, that although OOPC in small portion can be successfully used as a medicinal mushroom fruiting bodies cultivating substrate, their use is rational only, if no other substrate composing materials can be found or when OOPC usage solves the problem of its deposition.

Slovenian. Oljčne tropine (OT) predstavljajo odpadek s škodljivim vplivom na okolje in omejenimi možnostmi uporabe. OT imajo malo ali nobene uporabne vrednosti, zaradi česar se išče načine za njihovo alternativno uporabo. V naših poizkusih smo preizkušali substrate iz različnih deležev OT, pšeničnih otrobov, zdrobljenega koruznega zrnja in bukove žagovine za gojenje trosnjakov gliv Ganoderma lucidum, Lentinula edodes in Grifola frondosa. S povečevanjem deleža OT v substratu smo opazili trend zmanjševanja biološke učinkovitosti obroda. Rezultati kažejo, da čeprav lahko OT v manjših deležih uspešno uporabimo za substrat za gojenje trosnjakov, je to smotrno le v primerih, ko ni na voljo drugih  primernejših sestavin substrata ali takrat, ko je dodatek OT namenjem preprečavanju negativnih vplivov teh odpadkov na okolje.
